zrickkid, The VDI all depends on the ground, surrounding trash and iron and depth. These were finds at 2 different locations. I only use the VDI as a reference. (gosh, it could be this type of thing). I use the sound of the target and depth reading to determine whether to dig or not. The items in each photo are from different sites. The 1st photo (fatty indian, LC, barber) was from a site with not much surrounding trash. The fatty was down about 8 - 9 inches, vdi in the 50's, a short but definately good sound. The LC I didn't notice the VDI, depth about 8 inches. The Barber gave a nice sound, VDI in the upper 70's, but bounced around some because of trash items surrounding it. Depth 7 inches.
The 2nd photo was from a very trashy, iron infested site. Sounds were iffy because of all the adjacent iron and trash. This site had to be worked slow and hovering the coil over the good sound sort of locked in the target. VDI was jumping around, the V nickel VDI was 2. The indians VDI were jumping 30 to 60. At this site it is common to pull a rusted nail in the same hole as the coin. Depth on the indians ranged from 5 to 9 inches. I use my digger to measure the depth. I won't be going out for a few days, have to let my arms heal. I don't know how Angel can dig the deep holes without feeling it afterwards.
